Flite 110-SA
Fault passage indicator
for overhead network
PE41017
Advantages
■ Flite 110-SA adjusts to the network voltage and frequency.
Using fault detectors makes it easier to locate faults on distribution networks.
The detector must adapt to the electrical network characteristics and be perfectly
visible to allow maintenance teams to quickly detect faulty network sections.
■ Flite 110-SA is configurable on site.
An overhead fault detector must be coordinated with the upstream protection system
whose trip threshold can vary according to its position on the MV network.
■ Flite 110-SA indicates permanent and transient faults with the same
indication light intensity.
A fault detector always indicates permanent faults, but utilities companies often also
want to find transient fault (a fault is considered to be “transient” when the upstream
protection device eliminates the fault during its reclosing cycle).
■ The indicator light is visible from a 360° angle.
Fault detection
Flite 110-SA is fitted with two sensors, one measuring the magnetical field
(image of the current) and one measuring the electrical field (image of the voltage).
■ Detects both short-circuits
and low current earth faults
b Self adaptation to network voltage
and frequency
b Highly visible red flash light
b Indicates both permanent
and transient faults
b User adjustable
Flite 110-SA is hooked directly onto the line without
any specific tooling.
When installed on a live conductor, Flite 110-SA
automatically adapts to the network voltage frequency,
then activates the fault detection function.
Fault types: a fault is expressed either
in terms of the exceeding of an absolute current
threshold (Imax, phase-phase fault), or a variation
in current over a given time (di/dt, phase-earth fault).
Flite 110-SA indicates both transient faults and
permanent faults. The transient fault detection function
can be disabled.
Fault confirmation: in order to avoid any indication
errors, faults are confirmed by the lack of voltage after
the upstream protection device has tripped.
Inrush current filter: when the line is energized,
a time delay filters inrush currents due to transformer
magnetization.
Resetting: permanent fault indication is automatically
cleared when voltage returns to the MV line or following
a time delay. Flite 110-SA checks that the MV supply
has stabilized before resetting itself.
Change in transient faults: if a permanent fault occurs
whilst the device is already indicating a transient fault,
the flashing automatically changes from transient to permanent, thus enabling
maintenance staff to deal with faults according to their priority level.
